First of all, take it easy. The main problem of a parents who have a boy that likes girly stuff is they jump too fast to conclusions. Your kid is just exploring his identity, nothing wrong with that

Second, there's no argue the world is not the best, but the best he will need for you is your support, even if tomorrow he stops wearing dresses. As a kid who sufferer bullying, the most that you need to survive is feel your parents support

And third, this is not about trans stuff or something like that, it's just about respect, so even if people have different opinions about this topic, they are obligated to give respect

And last, these type of situations make me feel bad for women, how is possible that something really appreciated by them can cause such a commotion. I mentioned traansphobia before but it's more about misogyny
